Description
Source selection (see Terms and abbreviations
152).
Defines the flux reference when parameter
reference select is set to
User-defined flux reference.
This parameter can be used to improve the control dynamics
of a synchronous reluctance motor or a salient permanent
magnet synchronous motor.
As a rule of thumb, define a level to which the output torque
must rise with minimum delay. This will increase the motor
current and improve the torque response at low speeds.
Optimizer torque limit.
An optimization setting for balancing between control
performance and motor noise level.
Note: This is an expert level parameter and should not be
adjusted without appropriate skill.
Control performance optimized for long motor cables.
Minimizes motor noise.
Note: This setting requires derating. Refer to the rating data
in the Hardware manual.
Control performance optimized for cyclic load applications.
Note: This setting is not suitable for long motor cables.
This setting is to be used by ABB-authorized service
personnel only.
Note: This setting may require derating. Refer to the rating
data in the Hardware manual.
Enables signal injection. A high-frequency alternating signal
is injected into the motor at low speeds to improve the
stability of torque control. Signal injection can be enabled
with different amplitude levels.
Notes:
• This is an expert level parameter and should not be
adjusted without appropriate skill.
• Use as low a level as possible that gives satisfactory
performance.
• Signal injection cannot be applied to asynchronous
motors.
Signal injection disabled.
Signal injection enabled with an amplitude level of 5%.
Signal injection enabled with an amplitude level of 10%.
Signal injection enabled with an amplitude level of 15%.
Signal injection enabled with an amplitude level of 20%.
Rotor time constant tuning.
This parameter can be used to improve torque accuracy in
closed-loop control of an induction motor. Normally, the
motor identification run provides sufficient torque accuracy,
but manual fine-tuning can be applied in exceptionally
demanding applications to achieve optimal
performance.Note: This is an expert level parameter and
should not be adjusted without appropriate skill.
